custom_components.smartthinq_sensors.light.LGELight does not set supported color modes, this will stop working

Describe the bug
When restarting Home Assistant, there is an error in the logs. which is related to the light entity from microwave.

Logger: homeassistant.components.light
Source: components/light/__init__.py:1267
integration: Light (documentation, issues)
First occurred: 12:42:36 AM (1 occurrences)
Last logged: 12:42:36 AM

None (<class 'custom_components.smartthinq_sensors.light.LGELight'>) does not set supported color modes, this will stop working in Home Assistant Core 2025.3, please create a bug report at https://github.com/ollo69/ha-smartthinq-sensors/issues

Here is a blog post on HA Developers site about change and link to developer docs for light color mode. It seems that it's now required to specify ColorMode.ONOFF in supported_color_modes instead of leaving it blank.

Note: There is also a ColorMode.BRIGHTNESS but I don't know if that fits since you have to change brightness via effect. So I think ColorMode.ONOFF is most accurate for the microwave light.

Below is screenshot and state of the light entity from my microwave.
